Tires question

Uh, not exactly. In most cases, they are stated as separate items and are not linked - like this: Max Load XXXX, Max Pressure YY.

If you want to read up a bit on the subject:

Barry's Tire Tech

The issue is addressed when I talk about the "notes on page 1-34".

Well I wish I could sell the tires from the Fiero and get some new tires for the Neon but if you know anything about the 88 Pontiac Fiero you know that they are very hard to come by and so it would be hard to find anyone who wants them.-----Also to reply to everyone and the whole argument over psi, I'm not going to go over the max. It's not because of any specific reason besides: it's the max, I will go up to it, but not over.

If you have good tread on the fiero tires switch to those and sell the tires of the neon rims. Keep the rims and then when you eventually need to switch the tires out on the fiero rims if you don't like the fieros buy tires for the neon rims and sell the fieros with old tires mounted. This is assuming its going to fit. If they are mounted put it on a jack and switch the tires. Look carefully at the first one and see if it looks like it will fit. Put it down check the tires and the wheel well. If it looks too close abandone the idea.

The wheel will not seat quite right since the other tires/wheels are smaller so if its pretty reasonably close to being ok switch them all and then check again.

Hey everyone, this is a big update! I put the tires on the Neon, I dont really like it, it rides higher, feels like it weighs a ton but here are the exact specs. The other 4 tires on it originally were: Radial Classic p185/65R14 35max psi.....(2) Goodyear integrity p185/65r14 44max psi *one of these will not stay over 20psi* and the other is a Radial LTE Futura 2000 P185/65R14 44max psi..... The New tires are (4) Perelli P3000 P205/60R15 44max psi..... The first 4 tires weighted 30 pounds each and the new Perellis weight 39 pounds a piece which means I am lugging around an extra 36pounds! :-(

Unfortunately since its rotational mass that is proportional to your speed you are lugging effectively at least twice that.

Fortunately Pirelli makes good tires. Also you likely will see gains because the pressure will remain high(I would recommend 40-44(towards the low end because I am a little nervous about putting that much)). Also you will obviously save on having to pump the tires every week

The most important thing is you aren't driving on low tread and also importantly you have the same tread pattern on all 4 tires now. Having different tread can have advantages(in racing applications where the rear needs to grip evenly and the front needs to grip and turn under heavy lateral acceleration, but only in Rally because track racing(dry) they are smooth). But it also could pose a slight issue in inclement weather if one tire were designed with a different grip pattern it could weight shift from one part of the tire to another(where its tread is designed to grip) and the slight weight shift could result in a loss of traction.

Noob - the tires still stay clear of the wheel well insides after all that dia change?

Yeah and I can turn just fine, Have not hit a bump yet that has been crazy.

So I'm trying to get rid of the Fiero tires, If they do sell which tire should I buy that are 185/65R14 ? The Michelin Radial X tires right? because that is what I'm planning on since they are on the top of the All Season tires list for low-rolling resistance in another post I saw on here.

Look for an active Fiero message board. There must be one. Might be a way to find a buyer for your Fiero wheels. Or of course, FleaBay. The tires likely fit plenty of other cars so you can put them on CraigsList.

If ya don't find the Michelin Radial X's - or if you don't like the price -
Use TireRack.com's specs pages to find the max psi and also the weight of any tire you're considering.

I ended up with Kumho Solus KR21's. They are a bit heavier than other tires of same size so I kinda wish I'd found a tire I like that's a bit lighter than what I got. Outside-a that, I do like the Kumhos fine and the price was excellent.
